Problem type

You have just uploaded your first video as a content creator.

Curious about which audiences you should be targeting, you have gathered data about $N$ ~N~ $(1 \le N \le 3 \cdot 10^5)$ ~(1 \le N \le 3 \cdot 10^5)~ different viewers. Specifically, you know the ages $x_i$ ~x_i~ $(1 \le x_i \le 10^9)$ ~(1 \le x_i \le 10^9)~ of every single person that has watched your video.

Given $Q$ ~Q~ $(1 \le Q \le 3 \cdot 10^5)$ ~(1 \le Q \le 3 \cdot 10^5)~ different queries, how many people between the ages of $a$ ~a~ and $b$ ~b~ inclusive $(1 \le a, b \le 10^9)$ ~(1 \le a, b \le 10^9)~ have watched your video?

Input Specification

The first line of input contains an integer $N$ ~N~.

The second line of input contains $N$ ~N~ space-separated integers $x_i$ ~x_i~.

The third line of input contains an integer $Q$ ~Q~.

The next $Q$ ~Q~ lines of input each contain $2$ ~2~ space-separated integers $a$ ~a~ and $b$ ~b~ $(a \le b)$ ~(a \le b)~.

Output Specification

For each query, output the total number of viewers between the ages of $a$ ~a~ and $b$ ~b~ inclusive.
